In the game, Chu You and Zhao Feiyan are looking at the sixth auction item, a very special item.
A forbidden city without a name: Aerial City, the Air Fortress Guild! Once a player soul-prints it, they become the owner. When used in the wilderness, it immediately transforms into a small fortress, floating in the sky. The owner can control its aerial drift. As the guild level advances, the size of the fortress expands. The owner can merge the guild with the object, shifting the guild buildings to float on top of the Aerial City.
The Aerial City lacks the effect brought by the sphere of influence of the guild. The guild established in the Aerial City will not have any sphere of influence, nor will it be influenced by other guilds' spheres of influence, and can directly land next to other guilds.
